Robust Observer-based Fuzzy Control for Variable Speed Wind Power System

AbstractIn this paper, the observer-based control for stabilizing the variable speed wind power (VSWP) system is proposed. For achieving the robust stability, we deal with the parametric uncertainties of the concerned system which is based on the Takagi-Sugeno (T–S) fuzzy model. Also, we derive the observer-based models preserving the property and structure of the uncertainties. The sufficient conditions for output feedback stabilizing controller designs are given in terms of solutions to a set of linear matrix inequalities (LMIs). The simulation results for VSWP system are demonstrated to visualize the feasibility of the proposed method.
